I’m sure you’ve heard people tell you that Unix (and Linux) is a multiuser/multitasking operating system. But, what does that mean ?
Well, for one, you can create multiple users on linux and let all of them use the machine at the same time, by letting them login remotely (We’ll cover this later). And thus, Linux is a multiuser operating system.
Multitasking is a little more complicated.
You see, a Unix system at any time is always running more than one programs simultaneously. Ah, but I am only running my browser, you ask …
First of all I’ll get my credentials out of the way. I have been using computers since the last 10 or so years. That’s not much by a lot of people standards, but I like to brag about it anyway !
I used windows for the first year of my computer using life, got bored, moved to Linux, was fascinated and used Redhat, fedora, debian, slackware, ubuntu for the next 6 or so years.
I then got myself a Mac, a 2004 model iBook (I like the way Macheads use the year …
MYSTIC IN BALI
Having seen tons of banners and being a hard core Chinese food fan, I decided to check out this place with my two friends. Considering its a second restaurant from those who run “Big Chill” (one of the best Italian joints in Delhi), this place already has a great reputation to back it up, but will it live up to its Italian brothers? Thats what i went to find out?
The decor as such is more Bhutanese than Chinese. Since I have been to Bhutan, i recognized a lot …
The Manali to Leh road route is considered by many to be the greatest and arguably the toughest motorcycling road in the world.
Every year, dozens of bikers from all over the world ride over this road, which crosses over some of the highest mountain passes of the world.
The road is open from the end of May to about October, give or take a few weeks. The exact timings are dictated by the amount of snowfall that the passes recieve each year.
“UNIX is basically a simple operating system, but you have to be a genius to understand the simplicity.”
- Dennis Ritchie
Dennis Ritchie is one of the creators of Unix and the above quote summarizes the philosophy behind Unix. The Unix command line is terse by design and it can take a new user a long time to understand (and remember) the nuances of a particular command line.
Fret not, cause man is at hand.
man is the unix/linux command line utility designed to display documentation about a given command. For example, suppose you’ve …

In the last post of this series, we learned about logging in to a Linux box, creating a new non superuser account and start using that.
In this post we’ll learn how to start working with files. Creating, deleting and managing files is the reason you use a computer, right ?
Unix has a concept of directories, which is the same as a folder on Windows.
To list all the files in the current directory, use the following command:
$ ls
This will give you a list of directories in what is called the wide …
I have a confession to make. I’m a Unix guy, have always been and will always be. I’ve been using Unix for the last 10 years or so and will continue using it for as long as I can. There is something about the simplicity of the unix command line that none of the flashier operating systems can match.
I’ve also been interviewing people with basic Unix skills for various positions over the last couple of years. For some reason, I’ve found that Indian college curriculum doesn’t put too much emphasis …
The Boy Who Left Home to find out about the Shiver
How many times have you watched FRIENDS, Star Trek, DDLJ or your wedding video. Ever wondered why there are these things that we go back to again and again. The logical reason is that either they are entertaining every time you watch them OR there are some memories associated with them that you RE-LIVE each and every time you watch those videos.
Well, I have one of those awesome memories about watching “The Boy Who Left Home To Find Out About …
